Designation: C128-15 Standard Test Method for Relative Density (Specific Gravity) and Absorption of FineAggregate11.Scope1.1 This test method covers the determination of relativedensity (specific gravity) and the absorption of fine aggrcgates.The relative density (specific gravity), a dimensionless quality,is expressed as owen-dry (OD)., saturated-surface-dry (SSD), oras apparent relative density (specific gravity).The OD relativedensity is determined after drying the aggregate. The SSDrelative density and absorption are determined afier soaking theaggregate in water for a prescribed duration.1.2This test method is not intended to be used for light-weight aggregates that comply with Specification C332 Groupl aggregales.1.3The values stated in Sl units are to be regarded asstandard. No other units of measurement are included in thisstandard.1.4 The lext of this test method references notes andfootnotes that provide explanatory material. These notes andfootnotes (excluding those in tables and figures) shall not beconsidered as requirements of this test method.1.5 This standard does nor purport to address all of thesafery concerns.if anay. associated wih its use.
